25 Nov. 2011: Mirai

Nov.25Cloud / Rainy

All of the instruments and observations are working well.

Mirai is covered by the cloud, with the TPW of more than 55mm. The most
of the radar-echo is less organized. Surface wind is shifted from
southerly to easterly, and getting weak. Zonal component prevail
all of the troposphere.

Reflecting the widespread rain cloud, the salinity in the surface layer
(above 40m depth) decreases gradually. Still the cold and less-saline
water exists between 40m to 80m.
